UNITED STATES PATENT RUDOLF NEUGEBOREN, OF ANNABURG, GERMANY.

WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 774,363, Labecl "2?:'rcmber 8, 1904.

Application filed September 21, 1903. derial No. 174,073. (No model.)

To all whom it may concern.-

Be it known that 1, RUDOLF N GEBOREN, royal engine-shop foreman, a subect of the German Emperor, residing at 218 Torgaueiw strasse, in thetown of Annaburg, district of Halle-on-the-Saale, Kingdom of Prussia,German Empire, have invented a certain new and useful 1V ashing-Machinewith-Rotatable lrVashing-Drum, of which the following is aspecification.

This invention has reference to a washingmachine.

In the drawings, Figure 1 is a vertical section. Fig. 2 is a top view.Fig. 3 is a section on the line A B of Fig. 1.

1 is the water-tub of the machine, which is preferably made of wood andis provided with a water-tight inner lining of zinc.

2 is the washing-drum, which is provided with wooden ribs 3 in itsinterior and is free to rotate on the pivot 4, which is rigidly attachedto the bottom of the tub 1. In the lower part of the washing-drum is astationary rubber 5, which is rigidly secured to the pivot 1, the saidrubber 5 being also lined with ribs, as at 6. The said rubber 5 issecured to the pivot 4 at a certain distance from the bottom of thewashing-drum 2, which is also kept at a distance from the bottom of thetub 1 by a suitable washer secured to the lower end of the pivot 4E. Theopening in the bottom of the drum 2 is of larger diameter than the pivot4:, so as to form an annular slot around the said pivot, thusestablishing communication between the contents of the tub 1 and of thewashing-drum. The rubber 5 is so arranged and constructed as to leave aspace between its outer rim and the inner wall of the drum 2, so as toallow free circulation of the water into and throughout the interior ofthe said drum. At the open end of the washing-drum a rubber 7 isprovided with ribs 8 and is secured to the pivot 9, which enters in ahole of the cover 10 of the machine, so as to be freely rotatabletherein. At the upper end of the pivot 9 is secured the gear-wheel 11,which engages with the gear-wheel 13, secured to the shaft 12, uponwhich is also mounted the pinion 1a, which projects through the cut-outportion of the cover 10 and engages with the circular rack 16 of thewashing-drum 2. Upon the shaft 12 is also secured the lug 17, which inthe operative position of the machine engages with the groove 18 of thedriving-shaft 19 of the machine to which the crank-wheel 20 is secured,the crank portion 21 of which is preferably made of sufficient weight tocause the part 21 to be always directed downward. To this position ofthe part 21 corresponds the position of the groove 18, which is shown ing, Fig. 2 of the drawings, so that in this position the opening andclosing of the cover 10 can be effected without difficulty. 22 is astop-piece which in the open position of the cover prevents it fromdropping over to the rear.

23 represents rollers which are preferably arranged in the four cornersof the tub 1, so as to serve for securely guiding the upper end of thewashing-drum during its rotation.

21 is a latch which prevents accidental 0pening of the cover 10, Fig. 2.

25 is a faucet for allowing the water to escape from the tub 1.

26, 27, 28, and 29 are supports for the shafts 12 and 19.

The machine operates as follows: The tub 1 is first filled with water uptowithin about two-thirds of its capacity, the water also entering intothe interior of the washing-drum 2 through the annular slot between theparts 2 and 5 and through the opening in the bottom of the drum 2. Thenthe cover 10 of the machine is closed, so as to make the lug 17 of theshaft 12 engage with the groove 18 of the shaft 19, the shafts 12 and 19being thereby coupled together. If the crank 21 is rotated, thebevelgear-wheels 11 and 13 will cause the rotation of the upper rubber 7of the washing- 7 drum in one direction, while at the same time thewashing-drum 2 itself is rotated in the opposite direction by means ofthe toothed wheels 14 and 16, so that the linen contained in the drum iswashed in the most efficient manner and does not need to be finished bya subsequent washing operation.

I do not claim in this specification specifically the combination, witha stationary rub- Patented November 8, 1904. i

ber beneath the clothes, of a rotary rubber at the top of the clothes,as such devices are known; but

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. A washing-machine, comprising a tub, and a rotatable washing-drum inthe interior of said tub, a stationary rubber in the bottom thereof, anupper rubber and means to rotate the washing-drum in one direction andmeans to rotate the upper rubber simultaneously in the oppositedirection.

2. In a washing-machine the combination with a washing-tub and arevoluble rubber in the upper part and a stationary rubber in the lowerpart of the said washing-tub, of an intermediate open-headed, rotatablewashingdrum incasing said rubbers, a pivot in the bottom of the said tuband upon which the said washing-drum turns, the bottom of the said drumbeing slotted near the pivot and being arranged below the lower rubber,and means arranged on the cover of the washingtub, for rotating therotary drum and the rotary rubber in opposite directions.

3. A washing-machine, comprising in corn-.

bination, a tub, a rotatable washing-drum at the interior of the tub,operating means for said drum, a driving-shaft 19 and a crank at the endof said shaft, a secondary driving-shaft 12, for said drum a lug 17 onsaid secondary driving-shaft 12, a grooved part 18 on said driving-shaft19, the weight of the crank being distributed in such a manner that,when the machine is in the inoperative position, the said grooved partisalways upwardly directed, so as to allow of the cover 10 of the machinebeing opened and closed without difficulty when the machine is notworking.

In witness whereof I have hereunto set my hand in presence of witnesses.
